FRESH-AIR convEYEn.

Todll whom 'it may. concern: ".IBe it known that I, EMORY E. LAMB, a

citizen Oriole United States, residing at Pulaski, ih the county of Pulaski and Stateof 'Virginia, have invented a new and useful Fresh Air Conveyenof which the following is a specification.

This invention relatesfio fresh air con-.

veyers, and more particularly to that type of clevicesof this character utilized for conveying fresh air to the 'mouthof a person sleeping'within a closed room.

The objectof the invention is-to provide a simple formiof device of this character having a tubular skeleton frame ofnovel form which cannot collapse at any point and thus retard. the circulation of .air'and' which is J provided with a removable fabric covering from it.

. scribed and pointed out in the claims.v

In the accompanying drawings the prewhich can be readily detached and cleaned whenever desired; Another object is to provide a hood de-' signed to cover the head of the sleeper without retarding the movements thereof, said hood being of suflicient size to. permit a free ic'irculation of V pure and impure air into and A further object is to provide simple means for attaching the circulation tubes to the window casing, said means being adjustable;

towindows of difierent sizes.

With these and other objects in view, the invention consists of certain novel features of construction andbMribinat-ion of parts which will behereinafter more fully. de"- ferred form ofth'e inventionhas'been shown.

In said drawings Figure 1 is aview, partly in section and part1 in'elevation, of the complete apparatus. ig. 2 is an 'enlarged detail perspective view of a portion of the skeleton frame of one of the tubes.

'Fig. 3 is an enlarged section through one ofthe fasteners employed for attaching the inlet tube tothe hood'. Fig. 4 is a detail view of the extensible 'anel used within the window casing, 'one'o the parts of this panel beingbroken away.

Referring'to the figures by characters of reference,.11 designate superposedrings made of spring wire or other suitable m ate-- rial, said rin s being of different diameters and arranged to form a cone-shaped skelr? I ton frame, the" adjoining rings b eingiconnected by oppositely-disposed inclined. connect- Specification of Letters Patent.

ing links Qformed of spring wire or other similar material. ,"Extending from the apeX ofthis frame is the skeleton frame of the outlet-{tube of the apparatus, said skeleton frame consisting: of a series .of rings 8 formed preferably of'spri'ng wire and con nected by oppositely-disposed inclined links 4' also formed of spring wire. These rings are held the links spaced apart predeten mined distances at'all times. vIt willbe seen, therefore, that the skeleton frame of the hood and outlet tube are formed in one conftinuouspart Mounted on these two frames is agcasing consisting of a suitable closemesh fabric,'said casingcomprisin gated tubular member 5'and a conical memg an elonber 6', said conical member being disposed to extend over the rings 1 of the conical. frame, while the tubular member 5 extends over the rings 3 and their connections. .The

conical portion 6 of the casing extends beyond the lower or larger spring 1 to form a circular apron 7 designed to hang loosely about the head of the user so as to prevent the admission of air to the hood from the' surrounding atmosphere.

An opening 8 is formed within the conical casing'dnear. the bottom oropen end thereof, and arranged about this opening are fasteners of any desired form. In the drawings socket-members 9 of the well known ball sand-socket fastener type have been shown secured to the conical casing 6. The socket members 10' of these fasteners are securedto the flared end 11 of a fabric casing 12 arranged upon the skeleton frame 13 of'the inlet tube of the apparatus.

apparent, of course, that by snapping the fastener members10 ontothe members 9 the frame 13 and casing 12 can be firmly fats-- tenedto the hood casing 6. 'Both of the tubular casings-5 and 12 have their free ends surroundingmetallic thimbles 12,- and these casings may be detachably. secured to the thimbles in any preferred manner by means of elastic bands 14 or other securing devices.

Each thirnble 12 is designed to project through an opening 15 formed within a panel 16, and this panel-has an extension 17 slidably-'mounted thereon and held in proper relation thereto in. any preferred manner as by means of uide cleats 18. .If preferred, a screen 19 0 any desired form This skeleton frame is similar in all respects to the frame within the casing 5. It will be be arrangedftransversely' within each of the thiniblesilZ.

" In using the deviceherein descIiibed, -one panel 16 and \its extension is placed within the-Window casing A and above'one of the windbw sashes B, while another panel 16 and'its extension is placed within the win jdoi casing and below the other sash. The,

"thimble 12 of the inlet .tube is then inserted intothe opening in the lower panel while th'e thimble-12 1nthe outlet tubeis inserted in the opening in the upper. panel. Said ,lower tube'is' then attached to the hood 6 in the mannerdescribed, and the apparatus is then ready for use. The hood is .placed over the head of the usef and the apron 7 p Q will'obviously rest upon the uneven s.urface of the. bed andprevent the admission of anypartof the surrounding atmosphere'to theinterior of the hood. Each inhalation of the userwill cause'an amount of fresh air tobe drawn through the lowerorinlet tube v and into the hood and the vitiated air will 1 enced by the user.

-- be expelled subsequent to each exhalationthrough the upper oroutlet tube because of' the fact that it is lighter than the fresh air admitted through the lower tube. As the hood is comparatively large it will not interfere with the movements of the head therein and 1'10; discomfort therefore will be experi- -When it is desired to clean the casings 5,

r 6 and 12, the casing 12 is detached from the casing Sand can then be slipped off of the skeleton frame 13 and the casings 5 and 6' can also beremoved from the'frames contained therein. After they have been ,Washed and dried in any preferred manner they canefficient and will be' found particularly beneficial'to personssufl'ering from tuberculosis andv similar diseases requiring'fresh airin comprising a frame and a removable casing.
